STORE-SERVICE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 386,362, dated July 17,1888.

Application filed December 3, 1887. Serial No. 256,905.

To all whom zit may concern.-

Be it known that I, NnLsoN E. SPRING- sTEEN, of Royal Oak, in the countyof \Vayne and State of Michigan, have invented a new and usefulImprovement in Store-Service Apparatus, of which the following is aspecification.

My invention consists in an improvement in store-service apparatus,hereinafter fully described and claimed.

Figure 1 is an elevation, and Fig. 2 is a plan view ofa catch.

A and B represent two posts or supports, which may be secured to theceiling of astore and reach downward, or may extend upward from thefloor.

G and D represent two bell-crank levers, 0 being pivoted to the supportA and D to the support B by the pivots I J. On the long arm H ofbell-crank lever O and the long arm E of bell-crank lever D is fasteneda weight, W, which is preferably made adjustable on said arm, and may besecured by a setscrew, X, or in any other convenient way.

R represents a wire or other suitable track, whose ends are fastened tothe short arms G and F of the levers O D.

Q, represents acash or parcel car, of any ordinary construction, adaptedto run on the track R.

M and N represent catches secured to the supports A and B, as by collarsL and K, or in any other convenient way. The form of catch which I haveshown consists of two spring-jaws, O M, Fig. 2, adapted to engage with aspear-head, G, on the end of the frame of the cash-car Q; but any knownform of catch may be used, from which the car will be disengaged bybeing raised.

YYrepresent cords secured to the long arm of bell-crank levers O D, andreaching down to a convenient point to be grasped by asalesman.

The operation of my device is as follows: The car being at the end ofthe line held by (No model.)

post A, as shown in the drawings, the salesman, to return it to theother end of the line, pulls on the cord Y, which draws the long arm Hof the lever 0 into the position shown in dotted lines, thereby swingingthe short arm of the lever upward and raising projection P on the carout of the catch 0 M. This raises the end of the line attached to theshort arm G of the lever G, and at the same time actuates the lever D,so that its weighted arm rises and its short arm descends, therebylowering the end of the track attached to lever 1'), when the car Q runsdown the track and is caught by the catch N at the other end.

The weight XV serves to counterbalance the weight of the car Q when itis elevated for-the purpose of starting it.

I am aware that it is old to operate a store service apparatus byraising or lowering one end of a track; but am not aware that a singletrack or wire has ever been arranged as above described.

WVhat I claim as my invention, and desire to secure by Letters Patent,is-

1. In combination with two pivoted bellcrank levers, each having aweight on one of its arms, a single wire stretched between the otherarms of said levers, and a wheeled carriage on said track, substantiallyas shown and described.

2. In combination with the pivoted bellcrank levers O D, each having theweight \Y on its long arm, the single wire R, connected with the shortarms of said levers, the car Q, and a stationary catch supported beloweach lever, composed of two converging springarms so arranged that thecar can be lifted vertically out of engagement therewith, substantiall yas described.
